"Dr Thyssen and the surgical staff from AEC were very efficient and worked together as a very pleasant team. I would have given 5 stars except my phone call to SIG a week before the colonoscopy almost made me cancel. I called SIG to get a better clarification as to the pre-colonosocpy diet. Whoever I talked to seemingly got annoyed with me asking questions and I was told to stick to no seeds or I they wouldn't be able to do the procedure. How does anyone know they consider bananas to have seeds unless it's clearly stated. I found a diet sheet online from a credible university and followed that. Please include a diet sheet for patients to follow - people's interpretation of peel and and seeds vary. AEC didn't call me until the day before the case to pre-register me. For those two items I'm knocking off a star but the surgical team were the best."
